sub-titles inside of the category

Are you saying that it is not possible to do something like this?

Hi,

I want to create a category that displays products in list form but I want to separate the list
into sections with, maybe, a picture  but definitely a title to separate the products by section.

Example:  category  ->  saw parts

After clicking on the saw parts category there is some text and a picture or two about the saws.
Then there is a list of saws by manufacture under which the parts are listed and can be purchased.
(with maybe a picture by/ above the sub-titles)

Dewalt:

Blade bolt
crank handle             < -  This part is easy to do.  (just add products to the category.)
spindle
     :

Bosh:         <- How do I do this?   (sub-titles inside of the category)

top lever
blade bolt
handle screw
     :


Could someone help me by pointing me in the right direction?

Thanks,
Dave
